This is a simple configuration intended to run on Joyent with Manta storage.
Values for the default settings can be changed simply by editing this file,
uncommenting the relevant lines and adding your own settings. All you need to
do to get Juju deploying services on Joyent is to set:

sdc-user (Joyent login username)

sdc-key-id (finger print from ssh key uploaded to Joyent)

manta-user (login username -same as sdc-user)

manta-key-id (finger print from uploaded ssh key -same as sdc-key-id)

private-key-path (if your private is not at ~/.ssh/id_rsa)

Note: The private key is currently uploaded to the cloud in order to
remotely sign requests to the Joyent API. It is highly recommended that the
private key used in this way should not be a common SSH key you use for other
purposes, but a specific one used for the Joyent cloud.
Until there is a more robust workaround, you are strongly urged to generate a
new keypair for use with the Joyent cloud, and either set that file in your
private-key-path or paste it directly into the configuration as a private-key
value, instead of the private-key-path.
Remember to indent properly and to append a | after private-key to span
multiple lines.

You can retrieve these values easily from Joyent Dashboard at
https://my.joyent.com/main/#!/account. Click on your
name in the top-right and then the "Account" link from the drop down menu.

Note: During intial setup if you are having issues deploying charms contact
Joyent support @ https://help.joyent.com/home
to validate your account is enabled to provision virtual machines.
